About VCMI

The purpose of VCMI project is to rewrite the entire HOMM 3: WoG engine from scratch, giving it new and extended possibilities. We hope to support mods and new towns already made by fans but abandoned because of game code limitations.

VCMI is a fan-made open-source project in progress. We already allow support for maps of any sizes, higher resolutions and extended engine limits. However, although partially working, the game is not yet finished or fully playable. There are still many features and functionalities to add, both old and brand new.

VCMI is not yet a standalone program, it uses files and graphics from the original game. You need to have a version of Heroes 3 to install the files from (such as the one provided by GoG).

What VCMI is NOT

VCMI is not another mod. It does not aim to add new content or modify original mechanics. However, in the future it will be a base for other projects which do so.


Below are listed major features that are (not) implemented. For an exact list of implemented objects, artifacts, spells and so on, please check the VCMI Item Implementation Status spreadsheet.

What is done

  • Support for HoMM 3 graphics and maps
  • Choosing scenario options
  • Adventure map and interactions with all objects
  • Support for non-standard screen resolutions
  • Complete Town interface
  • Hero and Hero Meeting windows
  • Kingdom overview window
  • Battle interface, handling most of spells
  • Basic battle AI
  • Basic adventure AI
  • Campaigns
  • Hot-seat mode
  • Victory and loss conditions
  • Alliances
  • Stack Experience, Commanders
  • Mod support, including new towns, creatures and artifacts
  • Random map generator
  • Network game (How much that works is a little unkown but two-players should work)

What is still missing (see TODO list)

  • Network game
  • Possibly cheat-proof multiplayer mode
  • Many of WoG features, like Mithril
  • Scripting engine
  • Lots of minor features
  • AI town defense[1]

What has been added

  • Higher resolutions (1024x600, 1024x768, 1280x800, 1280x960, 1280x1024, 1366x768, 1440x900, 1600x1200, 1680x1080 and 1920x1080): resolution can be selected from the launcher.
  • Stack turn order queue: queue of stacks similar to Heroes V (although it doesn't follow its initiative mechanism). To toggle it on/off just press Q while in battle.
